Abstract
We analyse opinion diffusion in social networks, where a finite
set of individuals is connected in a directed graph and each
simultaneously changes their opinion to that of the majority
of their influencers. We study the algorithmic properties of
the fixed-point behaviour of such networks, showing that the
problem of establishing whether individuals converge to stable
opinions is PSPACE-complete
